The content
/var/log/univention/setup.log
lags in time during the initial (appliance mode) system setup via HTTP.
This is presumably due to buffering (/missing flushes) in the process writing that file.

Yes, cf. umc/python/setup/util.py → run_joinscript() → runit() , as discussed there should probably be a f.flush() after f.write(line).
